ART OF DETERGING RADIATORS Application filed December 17, 1830. SerialNo. 502,956.

This invention relates to the art of deterging radiators, and has for anobject to provide improved means for expelling from radiators employedin conjunction with automotive vehicles and the like, the several acintop plan,

cumulations formed within said radiator.

A further object of the invention is to provide a receptacle into whicha radiator may be introduced and to which, in such receptacle, may beattached the necessary facilities for carrying out the art which will behereinafter more fully explained.

A further object of the invention is to introduce into a radiator asolution of detergent material which will cause the sediment and otheraccumulations within the radiator to separate from the walls of theradiator and then to introduce suddenly and violently air under pressureto expel the detergent solution, together with the accumulated deposits.

A further object of the invention is to provide steps in the art ofdeterging a radiator, which consists in introducing water in a heatedcondition into the radiator to fill the said radiator to capacity,evacuating the radiator, filling with a detergent solution, permittingthe detergent solution to stand for a suflicient length of time toliberate the accumulations from the walls of the radiator, and thenshocking and expelling the detergent solution by the sudden concussiveadmission of air under pressure to form substantially an explosionwithin the radiator to expel the solution and dislodge any stillclinging accumulation from the walls or cells of the radiator.

The art which forms a part of the present invention may be carriedout'by the use of a great variety of mechanical devices, or with onlythe most rudimentary of such mechanical devices.

The showing in the drawings of a com plete installation for carrying outand practicing the art is no limitation upon the invention, and ismerely an illustration of a con-- venient and fully equippedinstallation for the purpose.

It comprises a tank 10, preferably having inclined sidewalls so that therear wall 11 is higher than the front wall 12.

The tank thus constructed is preferably covered over the greater portionof its area, leaving, however, an opening, as indicated at 13, foraccess thereto. The cover may be of any type desired.

A section 14 is shown in the drawin as being rigidly attached to thetank 10 with the section 15 hinged thereto by the hinges 16. This,however, maybevaried as occasi'on may make necessary or desirable.

Located somewhere adjacent to the tank 10 is a reservoir 17 which may beof substantially and usually the .ordinary 'stand boiler type with aninlet 18 for water, and a'hea-ter, indicated as a gas heater, 19.

Also located adjacentg tojth a second-reservoir 20 which inainlet21-Ic0ntrolledby a valve 22 mcontrolhug the flow of water fromthe'reservoir 17 into said reservoir 20. Provision is made for heatingthe reservoir 20, a gas pipe and burner 23 being indicated at Figure 1.

wk ;-1O..'i$ y I be similar .to the reservoirili'and is. provided. with.an

convenience may make desirable.

Extending into the opening 13 is a pipe 28 which is fitted with a nozzle29 to be hereinafter more fully described. The pipe 28 is connectedthrough a pipe 30 controlled by a valve 31 from the air reservoir 24.

A pipe 32 communicates also with the top of the water reservoir 17 andis controlled by a valve 33,making connection with the pipe 28 through acoupling 34. A pipe 35 extends from the chemical reservoir 20 and alsomakes connection with the pipe 28 after passing through a control valve36.

The nozzle 29 is provided with a semispherical end 37 as shown in detailat Figure 4, and a section of flexible tubing or hose 38 is attachedthereto, covering the semispherical part and the perforations 39 beingclosed, solution fr m the reservoir 20 therein.

The hose section 38 issecured upon the nozzle 29 by the hose clamp 40.This section of hose 38, as shown at Figure 3, is of suflicient lengthand flexibilit to be bent ,into the necessary angle to ma e connectionwith the normal outflow connection 41 of the radiator 42. The connection43 of the radiator is the connection normally at the top, the fillingcap 44 indicating such top position.

A cap 45 is provided for closing the connection 43 and the usualoverflow pipe 46 is shown as extending below the lower end of saidradiator.

In operation, the detergent material. is introduced into thereservoir 20through the filler openin 47 and water admitted thereto through t e pipe21, to form a solution of the necessary strength. The solution in thereservoir 20 is under pressure of air through the pi 48 from the airreservoir 24, t e water 1n the reservoir 17 being under pressure of thenormal water supply.

The radiator 42, being removed from the vehicle, is laid into the tankupon the strips or cleats 49 to support it off the bottom of the tank.The radiator cap at 44 is now put in position and the hose section 38attached to the lower connection 41.

Hot water from the reservoir 17 is now admitted through the pipe 32 bythe mao.

nipulation of the valve 33 to fill the radiator, such filling beingindicated byoverflow at the overflow pipe 46. The water is maintained inthe radiator until the radiator has reached a temperature substantiallyequivalent to boiling water or to water at very high temperature.

Air is now admitted through the valve 31 to expel the water from theradiator, or the r part thereof, and the air valve .ficient amount, thevalve 36 is closed, the

valve 33 again opened and water admitted to complete the filling of theradiator. Thus filled, it is allowed to stand for a short time, whichmay be from one minute on to any desired length of time, but a veryshort period of time will usually sufiice.

this solution admitted de-T of the solution, but

The normal inlet fitting 43 is now closed 7 by the cap 45 and the filleropening 44 o ned. The valve 31 is now suddenly opene wide so that airunder pressure from the tank 24 will pass through the nozzle 29 and theperforations 39 through the hose section 38 to the radiator, and willviolently and concussively shock and expel all of the fluid and solutionwithin the radiator, together with the deposits which have been loosenedand separated from the wallsof the radiator by the detergent solution,as well as liberating and separating and discharging others not yetcompletely separated.

The employment of this air concussively under pressure, suddenlyadmitted in considerable volume and great force to shock the radiatorparts, is believed to be the controlling'step in the art. It is,however, necessary that the air, as it enters the hose pipe 38, shall bebroken up to form air bubbles in the liquid as thereby a reverberatoryefiect is produced and it is therefore found desirable to employperforations 39, as shown in the semi-spherical part 37 of the nozzle.

It will be noted that one row of perfora I tions is practically coveredin normal position by the hose section 38. When introducing water, thesolution, or even air under normal conditions into the radiator, theouter row of perforations is not em loyed as it is covered by theflexible hose section 38. At the final inlet of the air, however, whenit is introduced in the radiator, in great volume and under great force,the force through the perforations expands the hose pipe 38, so that allof the perforations are employed for the air and the volume of air isthereby not diminished.

Of course, after the detergent solution-has been expelled from theradiator, watenis further employed from the reservoir 17 for the purposeof washing out any solution which may remain and further use of air nd apressure may be employed-and be repeated if found necessary ordesirable.

Of course, the invention herein illustrated may be in va Ways without(19-.

parting from the invention herein set forth and hereinafter claimed.

The invention is hereby claimed as follows:

1. The art of deter 'ng a radiator, consisting in fillingthQIQdlfltOI-Wlth a liquid, and then shocking and evacuating thecontained liquid violently by the sudden introduction of a large volumeof air under high pressure, said air being separated into several jetsas it is so introduced.

2. The art of deterging a. radiator consisting in filling a radiatorwith a liquid, and then producing a. violent concussive expulsion of theliquid, by the introduction of numerous jets of air under pressuresimultaneously to form a bubbling intermixture of air and waterthroughout the radiator.

3. The art of deteriing a radiator, consisting in introducing t ereinwater at a high temperature for the purpose of heating and expandi theradiator, expelling the heated water an suspended material from theradiator, introducing at a high temperature into the radiator adetergent solution, permitting the detergent solution to stand asuflicient length of time to perform a cleavage'ofthe deposits from thewalls of the radiator, introducingconcussiveli air underhigh pres,- sureto violently shoe and expel the detergent solution from the radiator,and flowing water therethrough to wash out the remaining solution anddeposits.
